Abstract

A broadcasting signal reception device according to an embodiment of the present invention may comprise: a reception unit for receiving, through the broadcasting network, a broadcasting signal including a first component of a DASH content which can be received through a broadcasting network and a broadband network; a delivery module for de-capsulating the received broadcasting signal, outputting LCT packets transmitted through one or more LCT channels, and parsing signaling information used for acquiring segments corresponding to the first component of the DASH content included in the LCT packets; and a decoder for decoding the acquired segments.

Claims

1. A broadcast signal reception method comprising:

receiving, by a broadcast network interface, a broadcast signal including Real-time Object delivery over Unidirectional Transport (ROUTE) packets and Service List Table (SLT) including different bootstrap information based on delivery protocols,

the bootstrap information including a source IP address, a destination IP address and a destination port of at least one Layered Coding Transport (LCT) channel for ROUTE-delivered services,

the bootstrap information including a destination IP address and a destination port of a MPEG Media Transport Protocol (MMTP) session for MMTP-delivered services,

the ROUTE packets including media presentation description (MPD) and media components belonging to a service, the media components being included in dynamic adaptive streaming over HTTP (DASH) representations carried over broadcast;

the MPD describing the DASH representations carried over broadcast and the MPD being capable of describing additional DASH representations delivered over broadband;

receiving, by a broadband network interface, the additional DASH representations delivered over broadband; and

requesting and obtaining, by a processor, missing data via broadband from a server based on HTTP request/response transaction when a broadcast signal reception device is unable to acquire an entire object delivered by ROUTE.

2. The broadcast signal reception method according to claim 1, the MPD is included in signaling information, the signaling information further includes information on the at least one LCT channel and at least one piece of source flow information transmitted by the at least one LCT channel, and the source flow information further includes information for acquiring DASH segments.

3. The broadcast signal reception method according to claim 2, the signaling information further includes information for identifying whether the corresponding media components are transmitted through a broadcast network or a broadband network.

4. The broadcast signal reception method according to claim 3, further comprises:

sending, by a DASH module, a request for the DASH segment to the server based on an availability time of the DASH segments calculated based on the MPD.

5. The broadcast signal reception method according to claim 2, the signaling information further includes first information including service identifier for a broadcast service and access information for second information,

wherein the second information includes the MPD,

wherein the access information includes destination Internet Protocol (IP) address for the second information, destination User Datagram Protocol (UDP) port number for the second information, and source IP address for the second information.

6. A broadcast signal reception device comprising:

a broadcast network interface to receive a broadcast signal including Real-time Object delivery over Unidirectional Transport (ROUTE) packets and Service List Table (SLT) including different bootstrap information based on delivery protocols,

the bootstrap information including a source IP address, a destination IP address and a destination port of at least one Layered Coding Transport (LCT) channel for ROUTE-delivered services,

the bootstrap information including a destination IP address and a destination port of a MPEG Media Transport Protocol (MMTP) session for MMTP-delivered services,

the ROUTE packets including media presentation description (MPD) and media components belonging to a service, the media components being included in dynamic adaptive streaming over HTTP (DASH) representations carried over broadcast;

the MPD describing the DASH representations carried over broadcast and the MPD being capable of describing additional DASH representations delivered over broadband;

a broadband network interface to receive the additional DASH representations delivered over broadband; and

a processor to request and obtain missing data via broadband from a server based on HTTP request/response transaction when the broadcast signal reception device is unable to acquire an entire object delivered by ROUTE.

7. The broadcast signal reception device according to claim 6, the MPD is included in signaling information, the signaling information further includes information on the at least one LCT channel and at least one piece of source flow information transmitted by the at least one LCT channel, and the source flow information further includes information for acquiring DASH segments.

8. The broadcast signal reception device according to claim 7, the signaling information further includes information for identifying whether the corresponding media components are transmitted through a broadcast network or a broadband network.

9. The broadcast signal reception device according to claim 8, further comprises a DASH module to send a request for the DASH segment to the server based on an availability time of the DASH segments calculated based on the MPD.

10. The broadcast signal reception device according to claim 7, the signaling information further includes first information including service identifier for a broadcast service and access information for second information,

wherein the second information includes the MPD,

wherein the access information includes destination Internet Protocol (IP) address for the second information, destination User Datagram Protocol (UDP) port number for the second information, and source IP address for the second information.
